6 12's or 4 15's?

[Narco]

the op asked for help and i dont want anyone else to close the thread b/c it has gotten so far off track. lets keep it on topic and it's all good. if not we'll delete the trash talk threads. if that doesnt work we go to plan B!

 

[Rose-Villian]

Ok Sorry People...

Got way off topic and Outa hand...

I think The OP should go with Ported... Much Louder than sealed, And Less stress on a Woofer...

Ide step it up to 6 type-R 12's and Justr get a Nice 3-4k Amp....

 

[01yukonslt]

im with blueflamed as far as the power you mentioned running 1000 rms per sub is a little much well twice what they are rated for so i wouldnt suggest that. i think 3-4k total watts would be perfect and pretty much maximize each subs output. 500-650rms or so per sub would be perfect

 

[blueflamed03]

1000 per..........sealed, more forgiving.

 

[B0$$MAN]

No need to bicker and clutter his thread guys, take it to PM if you wanna continue.

BOSSMANN, ive always been a 15" guy, just like em for some reason. So that would be my recommendation

4 15's would hit harder than 6 12's?

 

[clean454]

i think its all in the box
and its all TOTALLY PERSONAL PREF!!!!!

do what u want dont listen to these clowns!

do ur own trial and errors!

good luck and do a build thread!

 

[B0$$MAN]

I just have so many options that it's driving me nuts!!

1. 6 12" Alpine Type-R's Dual 2ohm, 5000w rms amp, ported box tuned to 33-34hz

2. 4 12" DD 9512 Dual 2ohm, 6000-8000w rms amp, ported box tuned to 33-34hz

3. 4 15" Alpine Type-R's Dual 2ohm, 4,000w rms amp, ported box tuned to 33-34hz

For electrical I have 250amp Alternator, Optima Yellow top (main battery), 2 Optima Blue Tops, Big 3, 10 Farad Capacitor.

Can you imagine a Crown 3,000 and 3 JBL GTi 15s? :drool It would sound so good and STILL get plenty loud.

on topic... I imagine if you do the 6 12s you'd wire them series on the subs to 4 ohms,
then parallel 3 together for a 1.3 nominal load, then series those two branches to wind up at 2.6 Nom.

Will your amp do the wattage you desire at ~3 ohms?


Also, have you listened to each sub at the wattages you propose and in an enclsoure similar in spec to what you will be using?

Long before i would commit to either idea, I;d want to know if a Single was going to play ok or sound like rice crispies with a lot of mechanical noise and cone cry.

For your Type R, listening to a single one ~1000W should not be too hard.

Dbs are logarithmic so 4 subs would be about 6 db louder than a single.

For your DD, you'd want to listen to a single sub at about 2,000 W, and that might be difficult.

Yea have fin with any crown equipment... jbl and crown split up so your shit out of luck if you burn something

And throw that garbage ass capacitor away do your self a favor bro...

So capacitors are no good?
I've read things about them that are for them and against them, I honestly don't think their is a big gain in having them.

I am looking for an amp that will put out what I want @ ~3ohms. Any ideas? Say 5,000w rms?

 

[thehoe92]

capacitors are ONLY good if you have zero voltage drop and you want to boost the peak bass hits

they are constantly discharging all their power when the bass hits, with no reserve which means your alternator is constantly having to keep it charged but over time your voltage just keeps going down because it can't keep up

batteries are MUCH better

and 5k RMS at 3 ohm is going to be hard to find

5k at 1ohm will be easier

 

[flawless06tahoe]

6 12's I love the tone they can get opposed to 15's that mainly just get that deep carrying bass.

 

[2003tahoe4]

I would do 4 15s

 

[B0$$MAN]

I think 12" is just the perfect sized subwoofer; hit real low, gets the highs, and it's just the all around best sub!

However, the amp is the tough part to charge the 6 type-r's. What should I do?

---------- Post added at 02:51 AM ---------- Previous post was at 02:02 AM ----------

I am looking at either 1 Cadence ZRS-C5 Amplifier or adding another Hifonics Brutus BXi 2610d Amplifier. What do you guys think? How many watts RMS would I get to each one of my 6 12" type-r's?

Stetsom Amps are pricey but they do rated power at 2ohms. You could go with a Stetsom 7K2D and it will prolly run 5K at 3 ohms. But to get that kind of power out of the amp, you will need a good sized batt bank along with your dual alt setup. And you might as well trash those optimas. oh, and more runs of 1/0 you would probably want 1 run to the back batteries from each alt. then one run from the front battery to the rear batts. so that is three runs. as far as subs go, If you want to really be loud, get away from the apline/ retail mentality. Move more into the competition subs. IE: DD, Fi, RE, Ascendant audio, Incriminator audio, RD, Sundown......

Oh and check out thise site. www.floridaspl.com my user name is leamangriffin on there. Tons of great advice from many of the top audio competitors. Also, tons of build logs to look through to get ideas. Also lots of cool ppl, and no ads or nut huggers like meades site.

 

[TnTahoe]

Go with the 6 12s so you can ride around bumpin Weebie - "I Got 6 12s" lol, and you only need 2 more of those

 

[blueflamed03]

Bo$$man, forget the caps, add a better alt or second batt.

 

[B0$$MAN]

Bo$$man, forget the caps, add a better alt or second batt.

As stated, I have 3 Optima batteries and a 250amp alternator.

 

[thehoe92]

anyone saying a 12 sounds better than a 15 or a 15 can play lower is wrong

its all in the box as Clean95 said

you can make a 12 play down to 20hz if you have the right box and the sub that will perform that low

so that shouldn't be any persuasion...

For the most part, I agree with you about the retail mentality, but I've been an Alpine fan for some time. The Type-R's are a legit subwoofer.

Ya I can find 5k watt rms @ 1 ohm all day, but if my 6 12's are wired to 2.6 ohm then I'll need my amp to produce the power @ 3 ohm.
